Referring nrst of all more particularly to the truck construction shown invFigures l to 4 inclusive, the invention is shown as applied to a fourwheel truck consisting essentially oi the truck frame 20 provided with pedestals 22 having cooperative relation with suitable journal boxes (not shown) or other journal means of wheel and axle assemblies 2l. The wheels are adapted to be engaged on each side thereof by inner and outer brake shoes 2t and 28. The brake heads 30 and I! o! said brake shoes are pivotally secured to inner and outer truck levers 3l and Il, the inner levers thereof being live truck levers, and the outer levers thereof being dead truck levers, the dead truck levers being fulcrumed as at Il to brackets III provided at the end of the truck trame.

Brake hangers l! are provided for the live truck levers. being Pivoted to the brake heads as at Il to which the live truck levers are also plvoted. and pivotally mounted as at Il to the bracket Il provided on the truck frame. The upper ends of the live truck levers I4 are pivotally conneeted as at il to the clevis or link 52, said link being engaged by the clevis or link Il, which in turn is pivotally mounted as at I6 on the dead equalizing or cylinder lever I8 at the one end ci the truck, and to the live equalizlng or cylinder lever Bil at the other end oi' the truck. The dead lever Il is iulcrumed as at l2 to selected apertures M provided in the bracket il, said bracket being positioned on the brake cylinder lli secured 50 to the truck frame 10. The live lever is pivoti ally mounted at its outer end as at 12 to the piston rod 1I adapted to be actuated by the suitable piston provided in the brake cylinder 08.

The dead and live levers i8 and GII are connectcontinuation in part oi 394,198, illed September ed intermediate their ends as at I0 and I0 by the Dull rod or cross bar 00, and the dead and live levers are adapted to be Supported on the truck frame by angle plate 02. The pairs of dead and live levers disposed on opposite sides of the wheel and axle assemblies 24 are pivotaily connected lntermediate their ends as at 04 and 80 by means oi' the pull or tie rods 00, said rods being disposed above the axles of the wheel and axle assemblies. The pull rods 00 are disposed on opposite sides of the wheel and are provided at their outer ends with the slack adjuster 00. The slack ad- .luster shown in Figures 5 and includes a trunnion member 02 having bearings or trunnions 04 on each side thereof for receiving the slotted heads 00 of pull rods 00, the rods being secured in position by means of the nuts and lock washers 00 and 00. An adjusting screw member |00 is secured to the trunnion member by means of the threaded portion |02 and the adjusting nut |04. The screw member is also provided on either side with bearings |00 and suitable washers |00. A cap ||0 serves to cover the exposed end of the adjusting screw and is itself threaded on the nut |04 a locking pin |00 fixing the cap to the nut |04 whereby the nut may be rotated to move member |00 by the threads |02 by rotating the cap ||0. The cap ||0 is provided with the spring pressed bali |01 adapted to engage spaced indentations in member 02 whereby tlie cap I I0 and the nut |04 are selectively fixed with respect to member 02 by the stop means formed by said spring Vpressed bail and the cooperating identations.

In assembling the slack adjuster withr the pull rods 00, each rod is secured to the trunnion member 94 and secured by the nuts 00. The dead truck levers 00 are also provided with suitable .openings intermediate their extremities for receiving the bearing members |00 on the adjusting screw |00 so that the dead levers and pull rods are maintained in adjusted position and are spaced as desired by varying the spacing between the members 02 and |00 through the adjusting nut |04. With the slack adiuster in position the washers |00 on the members |00 nd bearing engagement in various adjusted positions along the outer end or head 00 ot the pull rods 00. The adjuster, in combination with the adjustment of the lever 00 in the various openings 04, allows for a wide range oi' the adjustment ot the brake rigging.

In operation, when air is introduced to the operating cylinder 00, movement of the piston rod 14 toward the right es viewed in the figures causes the lever 00 to be moved to the right, exerting a pull on the pull rodl. Movement of the pufl rod-.00 causes pivotal movement, in4 a clockwise direction, of the dead lever 00, which in turn moves the live truck lever 04. Movement of the live truck lever causes movement of the pull rod 00, causing the outer brake shoes 20 to be set. Restricted movement of the pull rod 00 causes the live lever 04 to pivot around the point 00 vto set the inner brake shoe 20 at the right of the drawings. Restricted movement of the pull rod 00 causes the live lever 00 to pivot around the connection 10, which causes the brake shoes 20 and 20 at the left of the ligure to be set in a similar manner to the brake shoes 20 and 20 already described.

Referring now more particularly to the -wnstruction shown in Figures to 10 inclusive, the arrangement of the live and dead truck levers.

the connections therebetween, and the slack adjuster arrangement, are similar to that already described. The operating means therefor is varied. Either a brake cylinder operation is contemplated, or a hand operation, or both. The cylinder. if such is used, may be secured to either the car body or the truck frame.

In this construction, the live truck lever 34 at the left oi' the gure is connected through the clevis or link connection ||0 to they outer end of Y the dead lever ||0, the inner end thereof being pivotaily connected as at |20 to the bracket |22 secured to the truck frame 20. The live truck lever 34 at the right of the figure is pivotaily connected through the clevis or link connection |24 as at |20 to the outer end of the live lever |20. 'I'he dead and live levers ||0 and |20 are pivotaily connected intermediate the ends thereof, as at |00 and |02, to the pull rod |04, and the inner end of the lever |20 is pivotaily connectcd as at |00 to the pull rod |20 pivotaily connected as at |40 to the radius or equalizing lever |42. The hand or mechanical operating means may be secured to the equalizing rod |42.

In operation of this form of the invention, movement of the equalizing bar |42 to the right as viewed in the ilgures causes the pull rod |00 to move the live lever |20 toward the right. Movement of the live lever |20 toward the right causes a counter-clockwise movement of the dead lever ||0 through the puil rod |04. This movement of the dead and live levers causes operation of the brake shoes in a manner similar to that described with respect to Figures l and 2.

In the construction shown in Figures l1 to i4 inclusive, the brake rigging is shown as applied to a six-wheel truck. In this embodiment of the invention the truck frame |44 is provided with the depending pedestals |40 having cooperative relation with a suitable journal box or other journal means of the wheel and axle assemblies |40.
